You are almost there. Note that all you have to do is increment 1 to
the current 'value' for the key denoted by c. If you change the line
with get() to the following, it works as you want it to:
d[c]= 1 + d.get(c, 0)
Output:
{'a': 1, 'b': 1, 'o': 2, 'n': 1, 's': 2, 'r': 2, 'u': 1, 't': 1}
histogram2
{'a': 1, 'b': 1, 'o': 2, 'n': 1, 's': 2, 'r': 2, 'u': 1, 't': 1}
You were almost there. Good Luck.
-Amit.
